I have a KLX250 (2009, UK) which I'm currently cleaning in preparation of a part exchange. The rear aluminium rim has some pitting, as illustrated in the photo below: I've tried WonderWheels, aluminium polish, degreaser, and a wheel cleaning acid ( http://www.ebay.co.uk/itm/Alloy-Whe...ssories_Car_Care_Cleaning&hash=item4d0ad0c494 ), but none had any effect at all. I watched this YT vid in which resolving the issue looks very easy: http://www.youtube.com/watch?v=Want27Mvdc4 In the video the acid used was hydrofluoric acid but I can't seem to find any product containing this specific acid here in the UK. Please help me to repair my wheel rim! If anyone in the UK knows of any specific product that will do the job please post a link or let me know what it is. I don't know how important this is, meaning I don't know how much less I would get for my KLX in part-exchange if I am unable to fix the wheel rim pitting. Please let me know if you have any idea. I know the nasty condition of the (mild steel) spokes won't help either. Any tips on restoring them to a shine would also be welcome. Thanks.
